3. Stops menu
This main menu includes the parameters related to stopping the motor operated by the frequency converter.
Following parameters can be set here:
• normal fall time,
• mode of fall,
• parameters of fall with breakpoint,
• way of stop,
• data of the normal brake,
• time of spin out,
• data of the DC braking,
• data of the resistor brake,
• measure of keeping Udc,
• pulling of the brake
• Udc filtering

fall time
In means at both control and regulation the limitation of the frequency decrease slope.
(In case of stop, the fall time of the regulation acts even in control mode.
(The time needed for reaching 0 Hz starting from fmax or fnom.)

Explanation of the deceleration time
If the fall time is assigned to fmax (factory setting), the preset time is to be understood between 0 Hz and fmax.
There is possibility for assigning the fall time also to the nominal frequency of the motor (in menu 2-1-3).
The effective deceleration time (tdown) belonging to a given frequency can be calculated.
